PublicDateAtUSN: 2009-10-23
Candidate: CVE-2009-3767
PublicDate: 2009-10-23
References:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3767
http://www.ubuntu.com/usn/usn-858-1
Description:
libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other
versions, when OpenSSL is used, does not properly handle a '\0' character
in a domain name in the subject's Common Name (CN) field of an X.509
certificate, which allows man-in-the-middle attackers to spoof arbitrary
SSL servers via a crafted certificate issued by a legitimate Certification
Authority, a related issue to CVE-2009-2408.
Ubuntu-Description:
Notes:
mdeslaur> openldap in hardy and intrepid only have gnutls backend
mdeslaur> we compile jaunty-lucid with gnutls, not openssl
mdeslaur> so we're not vulnerable to this. (debian/configure.options)
mdeslaur>
mdeslaur> openldap2 in dapper has been patched with gnutls support, so
mdeslaur> not vulnerable. This is the library to which all dapper
mdeslaur> applications are linked, to not conflict with the openssl
mdeslaur> license.
mdeslaur>
mdeslaur> openldap2.2 in dapper uses openssl and is vulnerable.
